Navigation tips: Use the << and >> arrows on the menus for each regular section (Observers, Risks, etc.) to move to the previous and next day's news for that section. Use the Index menu item to access specific days through a calendar interface. To keep track of what's new each day, watch the Chronology section.

<&lt Reading: A large and, geologically speaking, relatively young impact crater has been discovered under the Greenland ice sheet, as detailed in a new science paper. See also an article at Astronomy magazine. There are indications that this impact could be the long-sought cause of the Younger Dryas climate episode some 13,000 years ago or less. And, on a distantly related note, BBC Travel has an interesting report on visiting what's left above water of the much larger and far older Chicxulub crater in Mexico's Yucatan Peninsula.

Notes: Ten times the distance to the Moon (ten LD) has no astronomical importance but is a useful boundary for reporting about transient natural objects that approach our planet's gravitational sphere of influence (SOI), which has a radius of about 2.41 LD from Earth's center. This puts a focus on some of the most important and very best NEO observation work, representative of the much larger NEO discovery and tracking effort. Object temporal distances are derived by A/CC from JPL Horizons data. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.

NEOCP Activity on 15 November '18

The MPC's NEO Confirmation Page has 47 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 47 objects listed. Of these, 35 were "one nighters." So far The Tracking News has counted a total of 65 listings on the NEOCP today.

Impact Risk Monitoring on 15 November '18

Summary Risk Table for Risk Assessments Updated Today (last checks: NEODyS at 2358 UTC)
See the CRT page for a list of all objects rated recently as risks and our ephemerides page for a list of risk-listed objects under current observation.
The time horizon for JPL and NEODyS listings is 100 years, and both post impact solutions beyond that for some special objects.
For the latest official risk assessments, and for explanations of the terminology, see the NASA/JPL Sentry and NEODyS CLOMON2 risk pages.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from a variant orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" to learn more.
